Footage of festival-goers passing a bag of urine over the crowd at Lollapalooza 2026 in Chicago has gone viral, sparking widespread criticism of poor audience behaviour and hygiene at the event. The clip has drawn significant backlash online, with many questioning why attendees would resort to this rather than using the festival's toilet facilities, and reflects a wider pattern of complaints about unruly crowd conduct at music events.

The video shows a bag of liquid inside a cardboard box being passed overhead through the audience, captioned "Passing a bag of pee through the crowd is NOT OK". This year's Lollapalooza featured acts including Olivia Dean, Charli XCX, Lorde, The Smashing Pumpkins and The xx. The incident follows similar hygiene-related complaints from artists such as Noah Kahan, who called for fans to stop defecating at venues, and Olivia Rodrigo, alongside separate reports of a Morgan Wallen fan allegedly urinating on other attendees and a Devilskin gig reportedly disrupted by mess in the mosh pit.
